Comment 94 for bug 39315

My very small contribution to Hug Day:

I'm having the same problem on my Intel Core Duo Thinkpad R60e with Edgy Beta using both the built-in keyboard and an external USB keyboard.

None of the following solutions work:
* The i8042.nomux=1 line in grub's menu.lst
* modprobe psmouse rate=40
* Killing gnome-power-man
* I've tried killing every module with "acpi" in it.
* plptools and tleds aren't (and have never been) installed.

It also occurs in xfce, but not in the full-screen text-only consoles available via the Ctrl+Alt+1 to Ctrl+Alt+6 shortcuts.

I've managed to fix the problem by downloading the "linux-386" kernel from Synaptic and booting with that rather than Edgy's default "linux-generic" kernel. Keyboard responsiveness seems better all-round - no pauses, no repeated characters.

So, from my perspective at least, it looks like Colonius is right (cheers, mate!) - this is in some way related to using an SMP kernel.
